Im just wondering how people first noticed the allergy and what they tried first? I have always believed one of my dogs to be head shy, but never really had and answer for why it started believing she just didn't like it. However today i am noticing after trimming her ears the skin inside seems to be very red and dry looking. This made me take a bit of a closer look at her and I'm noticing the bottom of her feet seem to be a bit red and i know she chews on the regularly. I know they haven't been flea treated in a long time so that will have to be my first step, but wondering what others did?
